Beydar Studies 1 constitutes the first volume of a new sub-series dedicated to the excavations at Tell Beydar (NE Syria), and its neighbourhood. It includes archaeological, environmental, and landscape archaeology papers. The contributions included in this first volume present progress reports on categories of objects discovered at Tell Beydar, 3rd Millennium BCE (sealings, beads and jewellery, basalt artefacts, metal finds, moulds and metallurgical workshops). Two studies concern the settlement pattern in the Syrian Jezirah and the Neolithic occupation of the region.
